Description

Technical Field

[0001] This invention relates to the field of pulverizing and dust removal equipment, specifically to an organic bentonite pulverizing and dust removal equipment. Background Technology

[0002] Organic bentonite is an inorganic mineral or organic ammonium compound. It is a fine chemical product made from bentonite as raw material by inserting an organic covering agent through ion exchange technology. After the production of organic bentonite, crushing is a key step in its processing and application. The core purpose is to optimize the physical form of the material to meet the requirements of subsequent production processes, improve product performance, and ultimately adapt to application scenarios in different fields.

[0003] When organic bentonite is crushed by a crusher, a large amount of dust will be generated inside the crusher because the organic bentonite is crushed into ultrafine dust. The crusher is connected to a bag filter to remove the dust generated during the crushing process. After the crushing is completed, the fine powder is discharged directly from the discharge port of the crusher.

[0004] When discharging fine powder from the discharge port of the crusher, if the amount of crushed material is small, the worker usually holds the cloth bag directly and aims it at the discharge bag at the discharge port to collect the fine powder. If there is a large amount of crushed organic bentonite, the collection box is pushed directly to the discharge port and aimed at the discharge bag again, so that the falling fine powder falls directly into the collection box. However, some dust will still be generated when the fine powder falls. Therefore, some dust will still be emitted during the collection process using the above method. If the worker is near the discharge port, the dust is easily inhaled into their body. Summary of the Invention

[0005] To overcome the above-mentioned defects, embodiments of the present invention provide an organic bentonite pulverizing and dust removal device, which solves the technical problem in the prior art that when collecting the crushed organic bentonite fine powder, some dust is generated when the fine powder falls, which is easily inhaled into the body by workers.

[0006] According to one aspect, at least one embodiment of the present invention provides an organic bentonite crushing and dust removal device, including a crusher, a discharge port at the bottom of the crusher, a feeding bag installed at the discharge port, a receiving box, a dust-blocking half-cover, a moving positioning component, a dust-blocking circular plate, and a bag-fixing ring. The receiving box is located below the crusher, a circular feed port at the top of the receiving box, and casters installed at the bottom of the receiving box. Two dust-blocking half-covers are provided, and both dust-blocking half-covers are slidably installed on the top of the receiving box via a synchronous moving component. The moving positioning component is located on the side of the receiving box and the crusher, and is used to position the receiving box to move directly below the discharge port. The dust-blocking circular plate is located on the top of the receiving box via a rotating component, and the bag-fixing ring is located on the rotating component.

[0007] Furthermore, the synchronous movement component includes a moving rack, a first support frame, a rotating shaft, a rotating gear, a first motor, and a drive component. The moving rack is fixedly installed on the sides of both dustproof half-covers. Two first support frames are fixedly installed on the top of the receiving box. The rotating shaft is rotatably mounted through each of the two first support frames. The rotating gear is fixedly installed on the side of the rotating shaft and meshes with the moving rack. The first motor is mounted on the top of the receiving box via a mounting bracket, and the output end of the first motor is coaxially connected to one of the rotating shafts. The drive component is located on the top of the receiving box.

[0008] Furthermore, the drive assembly includes a second support frame, a drive shaft, a drive gear, and a drive gear ring. The second support frame is fixedly installed on the top of the receiving box. The drive shaft is rotatably mounted on the second support frame. The drive gear is fixedly installed on both ends of the drive shaft. The drive gear ring is fixedly installed on both of the two rotating shafts, and the two drive gear rings mesh with the two drive gears respectively.

[0009] Furthermore, the moving positioning component includes positioning blocks and positioning rods. Two positioning blocks are fixedly installed on the side of the receiving box, and positioning grooves are opened on the side of the positioning blocks. Two positioning rods are fixedly installed on the side of the crusher, and the side of the positioning rods is adapted to the positioning grooves of the positioning blocks.

[0010] Furthermore, the rotating assembly includes a second motor and a connecting frame. The second motor is mounted on the top of the receiving box, and one end of the connecting frame is fixedly connected to the output end of the second motor. The bag fixing ring and the dust-blocking circular plate are both fixedly mounted on the connecting frame.

[0011] Furthermore, a dust cover is fixedly installed between the first support frame and the second support frame, and both the drive gear ring and the drive gear are located inside the dust cover.

[0012] Furthermore, the top of the dustproof half-cover has a semi-circular hole, and when the sides of the two dustproof half-covers are in contact, the sum of the radii of the two semi-circular holes is consistent with the diameter of the circular feed inlet of the receiving box.

[0013] Furthermore, the bottom edge of the dust-blocking circular plate is at the same horizontal level as the top edge of the dust-blocking half-cover.

[0014] Furthermore, when the sides of the two dustproof half-covers are in contact, the center of the semi-circular hole of the dustproof half-cover and the circle of the circular feed inlet of the receiving box are in the same vertical position.

[0015] Furthermore, the receiving box has a discharge chute on its side, and a box plate is hinged to the discharge chute.

[0016] The beneficial effects of this invention are as follows: In this invention, when collecting organic bentonite after crushing, the worker first moves the collecting box below the discharge port using a moving positioning component. Then, the feeding bag from the discharge port is inserted into the circular inlet of the collecting box. Subsequently, the synchronous moving component drives the two dustproof half-covers to move relative to each other, so that the two dustproof half-covers fit together. At this time, the circular inlet of the collecting box is located inside the two dustproof half-covers. Thus, when discharging, the dustproof half-covers can block some dust from escaping, and the feeding bag can continue to pass through the semi-circular hole of the dustproof half-cover. When discharging, the material supports the feeding bag, and the dustproof half-cover can block it. During material feeding, the rotating component can simultaneously rotate the bag fixing ring to the bottom of the feeding bag, allowing it to pass through the bag fixing ring and further fix the feeding bag. After feeding is completed, when moving the receiving box, the rotating component can block the semi-circular hole of the dustproof half cover with the dustproof circular plate, preventing dust from escaping from the semi-circular hole when moving the receiving box.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it.

[0021] To keep the drawings concise, each drawing only schematically shows the parts relevant to the invention; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0022] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

Therefore, they should not be construed as limitations on the present invention.

[0025] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0026] like Figures 1-7 As shown, an organic bentonite crushing and dust removal device according to an embodiment of the present invention is illustrated, including a crusher 1, a discharge port at the bottom of the crusher 1, a feeding bag installed at the discharge port, a receiving box 2, a dust-blocking half-cover 3, a moving positioning component, a dust-blocking circular plate 4, and a bag-fixing ring 5. The receiving box 2 is located below the crusher 1, a circular feed port at the top of the receiving box 2, and casters installed at the bottom of the receiving box 2. Two dust-blocking half-covers 3 are provided, and both dust-blocking half-covers 3 are slidably installed on the top of the receiving box 2 through a synchronous moving component. The moving positioning component is located on the side of the receiving box 2 and the crusher 1, and is used to position the receiving box 2 to move directly below the discharge port. The dust-blocking circular plate 4 is set on the top of the receiving box 2 through a rotating component, and the bag-fixing ring 5 is set on the rotating component.

[0027] like Figure 5 As shown, when crushing organic bentonite, crusher 1 uses a Raymond crusher, which can crush organic bentonite into fine powder. First, the workers put the organic bentonite into a hot air furnace or dryer through a conveyor belt or feeding device to control the internal moisture content to 2%-5% to avoid powder agglomeration due to moisture during grinding. After processing, the coarse particles are evenly fed into the interior of the Raymond crusher 1 through a feeder. Multiple grinding rollers in the main unit rotate at high speed with the main shaft and are squeezed outward under the action of centrifugal force, forming a crushing zone with the fixed grinding ring. After the organic bentonite particles enter this zone, they are repeatedly crushed and ground by the grinding rollers and grinding ring, and gradually broken into fine powder.

[0028] During crushing, a bag filter is installed on the side of the crusher 1. The large amount of dust generated during crushing can be controlled by the bag filter's design of "precise filtration + efficient dust removal + dust recovery". This meets the environmental emission requirements for crushing bentonite and avoids the waste of bentonite raw materials.

[0029] like Figure 2 , Figure 5 and Figure 7 As shown, before crushing, the operator first pushes the receiving box 2 to below the discharge port of the crusher 1 using a moving positioning component. The moving positioning component includes a positioning block 15 and a positioning rod 16. Two positioning blocks 15 are fixedly installed on the side of the receiving box 2, and the side of the positioning block 15 is provided with a positioning groove. Two positioning rods 16 are fixedly installed on the side of the crusher 1, and the side of the positioning rod 16 is matched with the positioning groove of the positioning block 15. Specifically, when the operator manually pushes the receiving box 2 to below the crusher 1, it stops after the positioning rod 16 is inserted into the positioning groove of the positioning block 15 on the side of the receiving box 2. At this time, the operator locks the caster wheels.

[0030] like Figure 4 As shown, after the receiving box 2 is fixed, the bag-fixing ring 5 is rotated to directly below the discharge port by the rotating assembly. The rotating assembly includes a second motor 17 and a connecting frame 18. The second motor 17 is installed on the top of the receiving box 2, and one end of the connecting frame 18 is fixedly connected to the output end of the second motor 17. The bag-fixing ring 5 and the dust-blocking circular plate 4 are both fixedly installed on the connecting frame 18. Specifically, the operator starts the second motor 17, and the output end of the second motor 17 drives the connecting frame 18 to rotate. The connecting frame 18 then drives the bag-fixing ring 5 to rotate to below the discharge port of the crusher 1. After the rotation is completed, the operator holds the feeding bag and pushes it through the bag-fixing ring 5 and then through the circular feed port of the receiving box 2, so that the discharge port of the feeding bag enters the receiving box 2.

[0031] like Figure 3As shown, after the passage is completed, the two dustproof half-covers 3 are moved relative to each other and fit together by the synchronous moving component. Because the top of the dustproof half-cover 3 has a semi-circular hole, and when the sides of the two dustproof half-covers 3 are in contact, the sum of the radii of the two semi-circular holes is consistent with the diameter of the circular feed inlet of the receiving box 2. When the sides of the two dustproof half-covers 3 are in contact, the center of the semi-circular hole of the dustproof half-cover 3 and the circle of the circular feed inlet of the receiving box 2 are in the same vertical position. Therefore, when the two dustproof half-covers 3 are in contact, the unloading bag can pass through the two semi-circular holes at the same time. The synchronous moving component includes a moving rack 6, a first support frame 7, a rotating shaft 8, a rotating gear 9, a first motor 10, and a drive component. The moving rack 6 is fixedly installed on the sides of both dustproof half-covers 3, and two first support frames are fixedly installed on the top of the receiving box 2. 7. A rotating shaft 8 is rotatably mounted through both first support frames 7. A rotating gear 9 is fixedly mounted on the side of the rotating shaft 8 and meshes with the moving rack 6. A first motor 10 is mounted on the top of the receiving box 2 through a mounting bracket, and the output end of the first motor 10 is coaxially connected to one of the rotating shafts 8. The drive assembly is located on the top of the receiving box 2. The drive assembly includes a second support frame 11, a drive shaft 12, a drive gear 13, and a drive gear ring 14. The second support frame 11 is fixedly mounted on the top of the receiving box 2. The drive shaft 12 is rotatably mounted through the second support frame 11. Drive gears 13 are fixedly mounted on both ends of the drive shaft 12. Drive gear rings 14 are fixedly mounted on both rotating shafts 8 and mesh with the two drive gears 13 respectively.

[0032] Specifically, the operator then starts the first motor 10. The output of the first motor 10 drives one of the rotating shafts 8 to rotate, which in turn drives one of the drive gear rings 14 to rotate. The drive gear ring 14 simultaneously drives the rotating gear 9 and one of the drive gears 13 to rotate. The rotating gear 9 drives one of the moving racks 6 to move forward, which in turn moves one of the dustproof half-covers 3 to the lower material bag. At the same time, the drive gear 13 drives the drive shaft 12 to rotate, which in turn drives the other drive gear 13 to rotate. The drive gear 13 drives the drive gear ring 14 that meshes with it to rotate. This drives another rotating shaft 8 and rotating gear 9 to rotate, which in turn drives another moving rack 6 and dustproof half cover 3 to move forward. After the two dustproof half covers 3 are in contact, they stop moving. Since a dust cover 19 is fixedly installed between the first support frame 7 and the second support frame 11, and the drive gear ring 14 and drive gear 13 are both located inside the dust cover 19, the protective cover can protect the meshing of the drive gear ring 14 and drive gear 13. When the material bag is inserted into the circular feed inlet of the bag inlet ring 5 and the receiving box 2, the two dustproof half covers 3 can be driven away to avoid blocking the workers from inserting the material bag into the circular feed inlet.

[0033] After completion, the staff starts and opens the discharge valve of the crusher 1. The fine powder flows down from the discharge port and then flows into the receiving box 2 through the discharge bag. When passing through the discharge bag, the discharge bag can be expanded to form a cylindrical shape. At this time, the bag fixing ring 5 and the semi-circular hole of the dust baffle 3 can block it, preventing the strong impact from causing it to move from side to side. The dust baffle 3 can also prevent dust from escaping during the discharge.

[0034] After the material is unloaded, the staff manually removes the material bag and then restarts the second motor 17 to rotate the dust-blocking disc 4 onto the semi-circular hole of the dust-blocking half-cover 3. Since the bottom of the dust-blocking disc 4 is at the same level as the top of the dust-blocking half-cover 3, the dust-blocking disc 4 can rotate to the top of the dust-blocking half-cover 3 to seal the semi-circular hole and prevent dust from escaping when the material box is moved. Then, the casters are released and the staff moves the receiving box 2 to the storage location. After the movement is completed, the receiving box 2 has a discharge chute on its side, and a box plate 20 is hinged to the discharge chute, allowing the box plate 20 to be opened to pour out the fine powder.

[0035] Working principle: When crushing organic bentonite, the operator first pushes the receiving box 2 below the discharge port of the crusher 1 until the positioning rod 16 is inserted into the positioning groove of the positioning block 15 on the side of the receiving box 2, and then stops. At this time, the caster wheel is locked. After locking, the second motor 17 is started. The output end of the second motor 17 drives the connecting frame 18 to rotate. The connecting frame 18 drives the bag fixing ring 5 to rotate below the discharge port of the crusher 1. After rotation, the feeding bag passes through the bag fixing ring 5 and then through the circular feed port of the receiving box 2, so that the discharge port of the feeding bag enters the receiving box 2. Then, the first motor 10 is started. The output end of the first motor 10 drives one of the rotating shafts 8 to rotate. The rotating shaft 8 drives one of the drive gear rings 14 to rotate. The drive gear ring 14 simultaneously drives the rotating gear 9 and one of the drive gears 13 to rotate. The rotating gear 9 drives one of the movable racks 6 to move forward, which in turn drives one of the dust-blocking half-covers 3 to move towards the feed bag. At the same time, the drive gear 13 drives the drive shaft 12 to rotate, and the drive shaft 12 drives the drive gear 13 at the other end to rotate. The drive gear 13 drives the drive gear ring 14 that meshes with it to rotate, and the drive gear ring 14 drives another rotating shaft 8 and the rotating gear 9 to rotate, which in turn drives another movable rack 6 and the dust-blocking half-cover 3 to move forward. After the two dust-blocking half-covers 3 are in contact, they stop moving. At this time, the feed bag passes through the semi-circular hole. Finally, the feed valve is activated, and the fine powder flows down from the discharge port and then flows into the receiving box 2 through the feed bag. When passing through the feed bag, the bag fixing ring 5 and the semi-circular hole of the dust-blocking half-cover 3 can block it, preventing it from moving left and right due to the strong impact. The dust-blocking half-cover 3 can also prevent dust from escaping during the feeding process.
